Chrome Plated and Tungsten Carbide Corrugator Roller for Single Facer Machine

Product Description

Corrugator Roller Brief Description

Corrugating rolls have an important role in forming the fluted layer of corrugated boards. Their surface quality, hardness, and wear resistance directly affect the precision of flute shaping, the stability of bonding, and the overall output of the production line. In an era where profit margins run razor-thin, choosing the right corrugating rolls becomes a key factor in reducing maintenance costs and improving production efficiency.

Application of Corrugator Roller

Corrugator rollers are precision-engineered steel cylinders used in the single facer section of corrugating machines to transform paper medium into a wavy, fluted shape under high heat and pressure. They are essential for creating durable, lightweight, and cushioned corrugated cardboard for packaging, providing structural strength, cushioning for shipping, and thermal insulation

Peripheral Heating Corrugator Roller

Peripheral heating corrugator roller are used in corrugating equipment to shape the fluted medium during the production of corrugated board. Unlike traditional rollers that use central steam pipes for heating, these corrugator rolls feature a modern design with multiple heating points distributed along the inner layer of the shell. This configuration enables much faster heat-up times, reaching optimal temperature in just five minutes.

Due to its efficient heat distribution, energy consumption is reduced by over 10% compared to conventional steam-heated rolls. The structure also helps minimize thermal deformation, which improves roll stability and overall performance. Service life is extended by approximately 20%, making them especially suitable for high-speed, high-efficiency production lines where both speed and durability are essential. These rolls are an excellent choice for plants looking to improve thermal response while reducing energy costs and downtime.

Our peripheral heating corrugator roller are compatible with a wide range of single facers, making them suitable for both international and domestic corrugated board production lines. They can be adapted to corrugating equipment from well-known brands such as BHS, Fosber, Mitsubishi, BW Papersystems, Marquip, Peters, Isowa, Agnati, Langston, JS, TCY, West River, Hsieh Hsu, K&H, XHL, Fuli, and Wanlian, among others. Whether for high-speed or heavy-duty applications, these corrugator roller can be tailored to meet the technical specifications and flute profiles required by different machine models.

Tungsten Carbide Coated Corrugator Roller

The tungsten carbide corrugator roller are coated using the supersonic flame spraying system, applying tungsten carbide powder at particle speeds above 800 m/s and flame temperatures below 1400°C. The coating process keeps the roll body temperature under 80°C, helping to minimize thermal stress during application.

The resulting surface achieves a hardness of HV0.3 > 1200 and a bonding strength of 6b > 70 N/mm², ensuring strong adhesion that remains stable over long-term use. The coating is dense, corrosion-resistant, and evenly applied, with a thickness deviation of less than ±0.01 mm. Roll runout is also controlled within 0.01 mm to ensure consistent precision. Compared to hard chrome plating, these corrugating roller offer 5 to 8 times higher wear resistance, reducing maintenance needs and extending service life. A post-coating polishing process brings surface roughness down to Ra 0.2–0.4, fully meeting the demands of high-speed corrugator lines. The durability and uniformity of the coating help maintain board thickness, reduce paper waste, and keep production stable. In real-world use, our tungsten carbide coated rolls have achieved service lives exceeding 50 million meters.

Tungsten carbide coated corrugating rolls are compatible with a wide range of single facers from both international and domestic brands. They can be adapted to corrugating equipment from BHS, Fosber, Mitsubishi, BW Papersystems, Marquip, Peters, Isowa, Agnati, JS, TCY, West River, Hsieh Hsu, K&H, and XHL, among others.

Chrome Plated Corrugator Roller

The drum flaker features a fully enclosed design, with access doors provided on both sides for maintenance. The top of the casing is equipped with an induced exhaust port, which connects to an external extraction unit to effectively remove odors and dust. Depending on the properties of the molten product being processed, the casing can be configured with inlet ports to introduce nitrogen—providing an inert atmosphere to prevent finished product oxidation—or to introduce cold air to enhance cooling efficiency and increase production capacity.

Packing Method

Cross-border transportation often takes one month or even longer. To prevent accidental damage during transportation, we have made special protection for the surface of each roller. The rollers are suspended in an steel frame and then protected with wooden boards. After the rollers are loaded into the container, they will be reinforced again to prevent potential risks caused by shaking during transportation.
